Review on Growth and Development of Multiple Ovulation and Embryo Transfer Technology in Cattle

The study was conducted in the world multiple ovulation and embryo transfer technology in cattle. In animal husbandry application of artificial insemination, estrus synchronization, multiple ovulation and embryo transfer used for improving animal breeding and genetics. Embryo is an egg that has already been fertilized by a sperm cell. Embryo transfer is a process by which an embryo is collected from a donor female and then transferred in to a recipient female which serves as surrogate mothers for the reminder of pregnancy. The International Embryo Transfer Society data retrieval committee presents the embryo transfer activity participated countries was 39 and 50 in 2014 and 2015 respectively. There are two methods of production of embryos from donor females; in vivo and in vitro fertilization. The number of embryos collected by in‐vivo in 2015 was 660,221, this result highest of 614,464 recorded in 2014. The value is increased by 7.45% from this contribution of North America (64.66%), Europe (22.4%) and South America (11.09%). Embryos collected by in-vitro fertilization were recorded 592,450 and 671,161in 2014 and 2015 respectively. According to the data United States and Canada are the leading embryo exporter countries, each exporting over 10,000 bovine in-vivo embryos each year followed by Australia and Argentina. It is expected South America, Africa and some Asia countries export only limited amounts of embryos, mainly due to risk of transmission diseases. I recommended that care will be taken during selection of donor and recipients, transfer procedures of embryos as well as in recipient management will be needed to enhance the efficiency by reducing risk of transmitting genetic disease via embryo transfer and the member state will be recorded appropriate data and send to international embryo transferring society for compiled.
